Hi Chuck,

If I remember correctly, the Accu-track could handle 15 watts. The
Bodine motor we used and it did work. The one motor that would not like
the freq changes was a Hurst DA motor. It hummed badly. My advice is to
e-mail a good friend of mine, John Vogt, since it was his drive assembly
that used this arrangement. Maybe his memory is better than mine ( 20
years ago ). You can reach him at:

Clear Skys,
